If one day the moon goes out of control and crashes into the earth, is there any way for human beings to stop it?

With the rapid development of science and technology, we humans have gone further and further on the road of space exploration. Changes in science and technology have shaped today's life. Although we didn't travel in space today, in the process of exploring the earth, we made many powerful weapons, such as nuclear weapons.

Nuclear weapons can be said to be the most powerful and destructive weapons on earth.

So can it really protect mankind from natural disasters? For example, the moon suddenly lost control and crashed into the earth. The moon is a satellite of the earth. Earth-moon system is a biological system that was born 4.5 billion years ago. The average distance from the moon to the earth is about 380,000 kilometers.

Because the earth's gravity successfully locked the moon in this distance. So when we look at the moon, you will find that we can only see one side of it and not the other. This is because the rotation and revolution time of the moon are the same.

So if the moon hits the earth, can humans stop it?

65 million years ago, an asteroid with a diameter of only 10 km destroyed most of life on earth, among which dinosaurs became extinct. Then according to classical mechanics, the closer the moon is to the earth, the faster it will be, because the gravity it bears is getting stronger and stronger. When it hits the earth, it will be more than twice as fast as before, so its power will be many times stronger than before.

If we humans use nuclear weapons at this time, can we destroy it?

If we are nuclear weapons, we can successfully blow it up. Then it will have a lot of most pieces falling on the earth. These fragments vary in size, and small fragments may be only a few tens of centimeters. And big things can be anywhere from a few meters, hundreds of meters or even thousands of meters.

So these fragments will do great harm to the earth if they fall to the earth. By then, although the moon has become a fragment, we humans will face a sudden meteorite shower. Later, because there was no protection from the moon. The earth's orbit will change. Once the earth's orbit changes, the global surface changes the most, and the most serious consequence is that the earth collides with other worlds or other celestial bodies.

If human beings cannot avoid it, they cannot change it. Running away is the only way out. All countries in the world have set up large-scale space cities in space, and 1000 space cities will be built within one hundred years, which can accommodate 1000 million people. People decide who will enter the space station by combining limited conditions and drawing lots.

Set up scientists, researchers, administrators, medical personnel, educators, industrial technicians, ordinary people, primary and secondary school students, children, etc. In different fields. Each group has various conditions and quota restrictions such as age, education, health, etc., and draws lots for all qualified people.

Accompanied by a large number of genetic specimens of earth creatures and some living species. Of course, there is also a treasure house of human knowledge, culture and art on earth. Stored in each space city.
